Only PulseAudio appears to return a list of available /dev/dsp* for cubeb consumers to allows users choose output/input at runtime. Mozilla doesn't maintain other backends, so it's up to the community to implement missing features. https://searchfox.org/mozilla-central/search?q=.enumerate_devices&path=media/libcubeb

## Missing features
|
|
|
|
Some features found on Windows, macOS and Linux are not implemented:
|
|
|
|
- Native audio (requires OSS backend, feature parity with ALSA or PulseAudio)
|
|
- Encrypted Media Extensions (requires Widevine CDM binary)
|
|
- Process sandboxing (requires Capsicum backend)
|
|
- Reduced memory usage (requires mozjemalloc)
|
|
- Crash Reporter (requires Google Breakpad and reproducible builds)
|
|
- Performance profiling (requires GeckoProfiler)
|
|
- Gamepad API (requires libusbhid backend)
|
|
- WebVR (requires open source runtime)
|
|
- TCP fast open
|
|
- `about:networking` (requires link state notification)
|
|
|
|
## Audio backend
|
|
|
|
To select non-default audio backend open `about:config` page and
|
|
create `media.cubeb.backend` preference. Supported values are: `alsa`,
|
|
`jack`, `pulse`, `pulse-rust`, `sndio`. Currently used backend can be
|
|
inspected on `about:support` page.
|
|
|
|
Microphone selection only works in `pulse` and `pulse-rust` backends.
|
|
Other backends are limited to `default` which is usually `/dev/dsp`,
|
|
so use virtual_oss to reroute microphones from non-default devices.
|
|
|
|
## smb:// issues
|
|
Network group, machine, and share browsing does not work correctly.
|
|
|
|
## sftp://
|
|
Only sftp access using public key authentication works. To easily
|
|
setup public key authentication to `remote_host`:
|
|
|
|
$ ssh-keygen
|
|
$ cat ~/.ssh/id_rsa.pub | ssh remote_host "cat >> .ssh/authorized_keys"
|
|
|
|
The SSH server on `remote_host` must allow pub key authentication.
